Inorganic Materials

The core competencies of Evonik Industries’ Inorganic Materials business unit are particle design, surface chemistry, and process technology for production of chlorosilanes and organosilanes. The business unit generated sales of about € 1.8 billion in fiscal 2009.

With our products we supply the tire, rubber, and paints & coatings industries, and producers of adhesives and sealants. Our products are also used in photovoltaics, foodstuffs and animal feeds, and print media.

Our silicon-based product portfolio, the only one of its kind in the world, includes the AEROSIL® fumed silicas and the precipitated specialty silica Sipernat® as well as pyrogenic specialty oxides and chloro- and organofunctional silanes. Siridion® chlorosilanes form the base for production of polycrystalline silicon, which in turn is the basic material for solar cell production.

With its Inorganic Materials business unit Evonik also offers a wide spectrum of custom designed products based on carbon black. Evonik is the only producer worldwide to offer the tire and rubber industries carbon blacks, precipitated silicas, and silanes from a single source. Our product groups occupy leading positions on the global market.
